Next-Generation
Mobile Networks and their Convergence with the Future Internet Architecture

671 Route 1
Abstract:
This talk provides a discussion of one of the central design
challenges associated with next-generation wireless systems - that of effectively
converging 3GPP-based mobile networks with the global Internet. Although the trend towards “flat” IP-based
architectures for cellular networks is well under way with LTE, significant
architectural evolution (or revolution enabled by emerging technologies such as
SDN) will be needed to achieve the goal of supporting the needs of mobile
devices and applications as “first-class” services on the Internet. Several emerging mobility service scenarios including
hetnet/small cell, multi-network access, M2M
(machine-to-machine) and V2V (vehicle-to-vehicle) are examined and related
network service requirements such as user mobility, disruption tolerance,
multi-homing, content addressability and context-aware delivery are
identified. Drawing from our experience
with the ongoing NSF-sponsored “MobilityFirst” future
Internet architecture project, we outline a possible protocol solution based on
the “GUID (Globally Unique Identifier) Service Layer” which enables a clean
separation of naming and addressing, and provides intrinsic support for a wide
variety of mobility services. Strategies
for evolutionary deployment of the proposed techniques are also discussed. The talk concludes with a brief outline of the
MobilityFirst proof-of-concept prototype currently
being deployed on the GENI meso-scale networking testbed.
